DISK HARROW.

Specification of Letters Patent.

Application filed July 3, 1911.

Patented Mar. 12, 1912.

Serial No. 636,627.

To all whom it may concern:

Be it known that I, J osnrn 1V. Kinney, a citizen of the United States,residing at Goldcreek, in the county of Powell and State of Montana,have invented certain new and useful Improvements in Disk Hal-rows, ofwhich the following is a specification.

The invention pertains particularly to novel means for relativeadjustment of the gangs of disks to most effectively perform theircutting action.

A further object of the invention is the means whereby the disk sectionsmay be simultaneously adjusted, or if desired the cor responding disksections of the gangs may be operated independently of the othersections.

Another object is to provide means for regulating the depth of cut ofthe disks which means may also be employed for steering purposes andalso to counteract any side draft which is not counterbalanced by theadjustment of the separate gangs.

For a full understanding of the present invention, reference is to behad to the following description and to the accompanying drawings, inwhich- Figure 1 is a side elevation of a machine embodying theinvention, the main operating lever being broken away; Fig. 2 is a frontelevation bringing out clearly the mounting of the controlling wheel;Fig. 3 is a top plan view, and Fig. 4 is a section on the line 4-4 ofFig. 3, and showing more clearly the cooperation of the main andauxiliary operating levers, the former being broken away.

Throughout the following. detail description and on the several figuresand drawings, similar parts are referred to by like referencecharacters.

Referring to the drawings the device comprising this invention consistsof a frame having a longitudinal beam 1 on which are mountedapproximately at the central and rear portions thereof the transversesupporting beams 2. Pivotally mounted on the transverse beams 2 on eachside of the beam 1 are the supporting frames 3, said frames havingdepending therefrom the supporting arms 4 having bearings at their lowerextremities for mounting of the axles 5. A plurality of disks 6 aremounted on the axles of each of the frames 3, said disks being shown asof the usual concave-convex form.

Between the front and rear transverse beams is located the depending arm7 in which is mounted the main operating lever 8, by means of the stubshaft 9, said stub shaft being keyed to the operating lever 8 as clearlyshown. in Fig. 4. At the lower extremity of the operating lever 8 ispivoted the link 10 which is connected at its opposite end to the innerend of the axle 5 of one of the front disk sections. At a suitabledistance above the stub shaft 9 is pivoted the link 11 which is securedto the inner end of the axle 5 of one of the rear sections of the disks.The main operating lever 8 thus described is preferably located on theright side of the beam 1 and is adapted to be adj usted in differentpositions by engaging with the notched segment 12 secured to the beam 1.On the opposite side of the beam 1 is located the auxiliary operatinglever 13 which is loosely mounted on the stub shaft 9 and has at itslower extremity a link 14 connecting at its other end to the innerextremity of the axle 5 of the other front disk section. Similarly tothe link 11 there is also secured on the auxiliary lever 13, the link 15which is connected at its other end to the inner extren'lity of the axleof the other rear disk section. As will be seen in Fig. 4, the auxiliarylever 13 normally engages with the key which connects the lever S to thestub shaft 9, but may be moved longitudinally of said shaft in order todisengage the same from the key and permit of independent adjustment ofthe front and rear disks on the corresponding side of the machine, saidadjustment being secured by engagement of the lever 13 with the notchedsegment 16.

At a suitable position in the front extremity of the beam 1 is pivotallymounted the controlling wheel 17 said wheel being mounted in theU-shaped member 18 extending at an angle to the post 19. At the upperend of the post 19 is located the arm 20 extending laterally therefromand having pivotally secured at its outer extremity the link 21. whichin turn is pivoted to the operating lever 22, said operating lever beingheld adjusted by means of engagement with the notched segment 23.

To permit of adjustment of the controlling wheel 17 to raise and lowerthe harrow, and thereby regulate the depth of cut of the disks, there isprovided a lever 24 which is pivotally secured intermediate its ends tothe post 19 above the beam 1, and pivotally mounted on said beam 1 atits lower end forward of the post 19. The proper depth may be regulatedby raising or lowering the lever 24 and permitting it to engage in thesegment 25 at the desired adjustment.

At the front extremity of the beam 1 may be provided a swivel 26 towhich the draft means may be attached.

At a suitable point between the front and rear transverse beams 2 issecured the standard 27 on which is mounted the seat 28, and it will beapparent that all of the operating levers will be within easy reach ofthe operator with the exception of the lever 24.

It will be noted from Fig. 3 of the drawings that the disks of thesections comprising the front gang of the harrow are mounted so as tothrow the soil being operated upon toward the right in a manner similarto the operation of the ordinary plow. Thus in passing over plowedground any soil which is not completely turned over will be thrown downfiat by the action of the front disks thereon. The disks in the sectionscomprising the rear gang are oppositely mounted to those of the frontgang and perform the usual cutting action of the soil as will be readilyapparent. The mounting of the disks as above described is veryadvantageous having in view the fact that there is no strip of soil leftuntouched between sections comprising gangs of the harrow or on the lapmade in the next round ofthe machine. To adjust the gangs at a properangle it is only necessary to move the lever 8 forward a desireddistance, said lever by virtue of the connection between the main leverand the auxiliary lever 13 operating the position of the front disk sections so as to throw the soil toward the right and simultaneouslypulling the disk sections of the rear gang into a position at anopposite angle to that of the front disks.

Under certain conditions it may be desirable to adjust the disks of oneside of the harrow at a greater angle than those of the disks on theopposite side, to accomplish which it is only necessary to press theauxiliary lever 13 outwardly, disengaging said lever from the key on thestub shaft 9 and thereby permitting independent adjustment of saidlever. The disk sections on either side may thus be adjusted as desired.

To provide means for regulating the depth of cutting action of the disksunder ordinary conditions the operator raises or lowers the lever 24:which would tend to prevent one side of the harrow from cutting deeperthan the other, if adjusted at a greater angle than the other sections.This adjustment of. the wheel 18 will remove nearly all of the sidedraft from the harrow. The wheel 17 also allows for steering the harrowas will readily be apparent.

Having thus described the invention, what is claimed as new is:

In a disk harrow, the combination of a frame, front and rear gangscomprising disk sections pivotally mounted on the frame, a mainoperating lever, a stub shaft pivotally mounted on the frame, a keyconnecting said lever to the stub shaft, links connecting said leverwith one of the front and rear disk sections, an auxiliary operatinglever loosely mounted on the stub shaft movable into and out ofengagement with the key aforesaid, and links connecting the auxiliarylever with the other of said front and rear disk sections.

In testimony whereof I aiiix my signature in presence of two witnesses.
